They are in NRA-ILA. Example:
A few days after this decision, the Fourth Circuit, clearly on a roll, ended its three-decision trifecta with a spectacular flourish in Kolbe v. Hogan – a decision upholding a Maryland ban on “assault weapons” and large capacity magazines because the banned assault weapons and magazines are arms that are beyond the reach or protection of the Second Amendment.

MD transport law:
Carrying and Transportation in Vehicles
It is unlawful for any person without a permit to wear or carry a handgun, openly or concealed, upon or about his person. It is also unlawful for any person to knowingly transport a handgun in any vehicle traveling on public roads, highways, waterways or airways, or upon roads or parking lots generally used by the public. This does not apply to any person wearing, carrying or transporting a handgun within the confines of real estate owned or leased by him, or on which he resides, or within the confines of a business establishment owned or leased by him.
A person may transport a handgun if they can demonstrate that the handgun is being carried, worn or transported:

• To or from a place of legal purchase or sale, or repair shop;
• Between a person’s bona fide residences, or between his residence and place of business, if the business is operated and substantially owned by that person;
• While engaged in, or traveling to and from a target shoot, formal or informal target practice, sport shooting event, hunting, trapping, or dog obedience training class or show; or
• By a bona fide gun collector who is moving any part or all of his gun collection from place to place for public or private exhibition.

NOTE THERE IS NO LEGAL PROVISION FOR TRANSPORTING UNDER ANY OTHER CONDITIONS, SUCH AS TOURISTS VISITING IN MD.
